Serpent 440181 Pack of 4 M3x19.5 Half-Thread Screws for Mini Spyder MT  [SER440181]

M3x19.5 half-thread fastener for Mini Spyder MT

Supplied as a 4-piece service pack, these half-threaded M3 screws (19.5 mm) are designed for the Serpent Mini Spyder MT. They are used where a partial thread is required to clamp components while an unthreaded shank preserves alignment and spacing.

These screws are intended for the Mini Spyder MT family and compatible SER440001 chassis components as listed by Serpent. Replace using the original mounting points, maintain correct thread engagement, and retain any washers or spacers to keep ride height consistent.

Assembly pointers: always hand-start fasteners to prevent cross-threading, apply torque evenly and avoid over-tightening on plastic or aluminium bosses. For installations exposed to vibration use a low-strength threadlocker and verify the hex key fits securely.
